Q.1	You're on a camping trip with a friend, and you desperately need clean water for drinking. The only option is a muddy stream full of leaves. You have some coffee filters with you. You fill a cup with the murky creek water and pass it through the filter. Based on the scenario, answer the following questions: A. What will happen when you try to filter the water through the coffee filter? B. Is this water safe for drinking?
	a) A: The filter will clog up quickly. B: Yes		b) A: The filtered water will be completely clear. B: Yes
	c) A: The filtered water will still be slightly cloudy. B: No		d) A: The filter will dissolve in the water. B: No

Q.2	Jane, an avid hiker, embarked on a mountain trek. As she ascended, she noticed a change in temperature. The higher she climbed, the colder it became. Gasping for breath, she wondered about the atmospheric layers. What atmospheric phenomenon primarily causes the decrease in temperature as Jane ascends the mountain?
	a) Increase in oxygen levels		b) Decrease in atmospheric pressure
	c) Decrease in altitude		d) Increase in humidity

Q.3	A group of students conducted an experiment to understand the greenhouse effect and its implications. What conclusion did they likely draw about the greenhouse effect?
	a) The greenhouse effect has no impact on Earth's temperature regulation.		b) Greenhouse gases trap heat, contributing to warming the Earth's surface.
	c) Greenhouse gases prevent sunlight from reaching Earth, causing cooling.		d) The greenhouse effect only affects certain regions but not the entire planet.

Q.4	The diagram shows a simplified version of the water cycle. Identify A given in sketch of water cycle.
	a) Infiltration		b) Sublimation
	c) Transpiration		d) Percolation

Q.5	A rapidly growing city is planning its expansion. Developer A proposes building high-rise apartments with minimal green space to maximise housing, while Developer B advocates for incorporating several large parks and green corridors throughout the development. A heated debate ensues, with arguments for and against each approach. Which developer makes the stronger case for the city's long-term well-being, and why?
	a) Developer A, as maximising housing density reduces transportation demands and promotes social interaction.		b) Developer B, as urban green spaces contribute to cleaner air, lower temperatures, and improved mental health of residents.
	c) Both developers offer equally valid points, and the decision should be based on economic considerations.		d) Neither developer, as further studies are needed on the impact of green spaces in megacities.

Q.6	While exploring climate change's impact on ocean health, a group of students identified a process significantly contributing to ocean acidification. What aspect of climate change primarily leads to the acidification of the ocean, affecting marine organisms?
